The Bulls shouldn't have any problem recruiting someone to play as well as Nero has for us. In his first year he was awful and nicknamed Chris Zero by the fans. Last year he was better and this year he was indifferent.
I expect Wardle, Crookes, Platt, Sykes and Menzies to share centre duties with hopefully a new signing too. Menzies is still capable of playing centre and has been comfortably better than anyone else at the club in that position.
Apparently Potter ok'd a fair offer to Nero based on how much he rates him. Nero wanted more money than he's currently on, result is Potter doesn't think he's worth it.
